Frequently Asked Questions

Can I resize an image without distorting it?▼
Yes. Enable the aspect ratio lock before resizing — changing width will automatically adjust height proportionally to prevent stretching or squishing.
What image formats can I resize?▼
JPG, PNG, WebP, and GIF are all supported for input. The resized image downloads as the same format as the original.
Is there a maximum image size I can resize?▼
There is no server-side file size limit. Processing happens in your browser, so very large images (over 20MP) may be slow on older devices.
Can I resize by percentage instead of exact pixels?▼
Yes. Switch to percentage mode and enter a value like 50% to halve both dimensions, or 200% to double them.
Are my images uploaded to a server?▼
No. The resize operation uses the HTML Canvas API entirely in your browser. Your images never leave your device.
